| Mix & Match Drive Types
|
Mix and match SSD, SAS and SATA drives to meet varying storage needs.
|
| Drive Stress Tests
|
Ensure that only the best quality drives go into Nexsan storage systems.
|
| System Drive Tests
|
Drives are tested in the storage system prior to being shipped to a customer.
|
| Anti-Vibration Design™
|
State-of-the-art vibration dampening maximizes reliability and performance.
|
| Cool Drive Technology™
|
Push/pull fans modules and specially designed air channels optimize drive cooling and reliability.
|
| Dual Active/Active Storage Controllers
|
Dual controllers provide additional horsepower and add additional I/O ports for Fibre Channel, iSCSI, or SASx4 access. All LUNs may be made visible on any or all FC, iSCSI, or SAS connections.
|
| Battery and Flash Protected Cache
|
Cache memory is protected via a battery built into the storage system. The battery has sufficient power to push all data from cache DDR3 RAM into flash where it will be preserved indefinitely. Cache data is synchronously mirrored between controllers to protect uncommitted writes in the event of controller failure.
|
| Two RAID Engines per controller
|
Two RAID engines reside on each E-Series controller to accelerate RAID operations, resulting in blazing fast sequential and random I/O performance.
|
| High Availability
|
All active components are redundant and hot-swappable including power supplies, fans, disks and controllers.
|
| Host Data Path Services
|
Included with every E-Series. Utilize multiple paths from a server to a LUN for increased bandwidth, as well as ensuring there is no single point-of-failure between the servers and their storage.
|
| Fibre Channel and iSCSI Multi-protocol Access
|
Both the Fibre Channel and iSCSI host ports can be utilized at the same time.
|
| Disk Provisioning
|
Place hard drives into RAID sets; determine the RAID type; establish hot spares and the RAID set auto-rebuild policies; and expose RAID sets as one or more logical address units (LUNs).
|
| RAID Hardware Management
|
Sets RAID levels and manages the caches in single or dual active/active controller configurations.
|
| LUN Masking and Binding
|
Ensures that only the hosts that are supposed to have access to a virtual disk get it. Hosts must authenticate before being granted access.
